Illustrative Math Algebra Unit Test

Is this mapping a function or not a function? 

• Function

• Not a Function

Does this mapping diagram represent a function?

• No, because there are repeating input values

• Yes, because there are no repeating input values

Is the equation linear, exponential, or quadratic?
y = 2x+ 4

• Linear

• Exponential

• Quadratic

• None of the above

• constant function
